jQuery autocomplete with python cgi as remote source

jQuery autocomplete with python cgi as remote source

I am new to python. I don't know how to get the data from python CGI script for jQuery autocomplete. The cgi script generates json data. For example. [{"product": "isoleucyl-tRNA synthetase"}

My html so far :

$(document).ready(function() {
        $( "#tags" ).autocomplete({
      source: "./search_term.cgi"
      select: function(event,ui) {
        var availableTags = ui.item.product;
      }
    });
  } );

Any help would be much appreciated.
